我在索引为 0 的 UITableViewCell 上有四个按钮。我为 0、1、2、3 之类的按钮设置了标签。当我在 0 标签的按钮上将 selected 属性设置为 NO 时，它显示以下错误：
-[UITableView set Selected:]: unrecognized selector sent to instance
但是其他按钮没有错误：
代码在这里：
UIButton *button1 = (UIButton *)[tableView viewWithTag:0];
[button1 setSelected:NO];
UIButton *button2 = (UIButton *)[tableView viewWithTag:2];
[button2 setSelected:NO];
UIButton *button3 = (UIButton *)[tableView viewWithTag:3];
[button3 setSelected:NO];
[button1 setBackgroundColor:[UIColor whiteColor]];
[button2 setBackgroundColor:[UIColor whiteColor]];
[button3 setBackgroundColor:[UIColor whiteColor]];
编辑代码：
- (IBAction)click:(id)sender
{
UIButton *theButton = (UIButton *)sender;
UITableViewCell *clickedCell = (UITableViewCell *)[[sender superview] superview];
NSIndexPath *clickedButtonPath = [tableView indexPathForCell:clickedCell];
NSLog(@"hi...%d",clickedButtonPath.row);
if(theButton.tag==0)
{
theButton.selected=YES;
[theButton setBackgroundColor:[UIColor redColor]];
UIButton *button1 = (UIButton *)[clickedCell viewWithTag:1];
[button1 setSelected:NO];
UIButton *button2 = (UIButton *)[clickedCell viewWithTag:2];
[button2 setSelected:NO];
UIButton *button3 = (UIButton *)[clickedCell viewWithTag:3];
[button3 setSelected:NO];
[button1 setBackgroundColor:[UIColor whiteColor]];
[button2 setBackgroundColor:[UIColor whiteColor]];
[button3 setBackgroundColor:[UIColor whiteColor]];
}
else if(theButton.tag==1)
{
theButton.selected=YES;
[theButton setBackgroundColor:[UIColor redColor]];
UIButton *button1 = (UIButton *)[clickedCell viewWithTag:0];
[button1 setSelected:NO];
UIButton *button2 = (UIButton *)[clickedCell viewWithTag:2];
[button2 setSelected:NO];
UIButton *button3 = (UIButton *)[clickedCell viewWithTag:3];
[button3 setSelected:NO];
[button1 setBackgroundColor:[UIColor whiteColor]];
[button2 setBackgroundColor:[UIColor whiteColor]];
[button3 setBackgroundColor:[UIColor whiteColor]];
}
else if(theButton.tag==2)
{
theButton.selected=YES;
[theButton setBackgroundColor:[UIColor redColor]];
UIButton *button1 = (UIButton *)[clickedCell viewWithTag:0];
[button1 setSelected:NO];
UIButton *button2 = (UIButton *)[clickedCell viewWithTag:1];
[button2 setSelected:NO];
UIButton *button3 = (UIButton *)[clickedCell viewWithTag:3];
[button3 setSelected:NO];
[button1 setBackgroundColor:[UIColor whiteColor]];
[button2 setBackgroundColor:[UIColor whiteColor]];
[button3 setBackgroundColor:[UIColor whiteColor]];
}
else if(theButton.tag==3)
{
theButton.selected=YES;
[theButton setBackgroundColor:[UIColor redColor]];
UIButton *button1 = (UIButton *)[clickedCell viewWithTag:0];
[button1 setSelected:NO];
UIButton *button2 = (UIButton *)[clickedCell viewWithTag:2];
[button2 setSelected:NO];
UIButton *button3 = (UIButton *)[clickedCell viewWithTag:1];
[button3 setSelected:NO];
[button1 setBackgroundColor:[UIColor whiteColor]];
[button2 setBackgroundColor:[UIColor whiteColor]];
[button3 setBackgroundColor:[UIColor whiteColor]];
}
}
